Please give me help! my system ---------- source : Yamaha dvds2500 - 2 Vrsm/ impedance not known SB3 - 2.1 Vrsm/ 220 ohm connection: RCA unbalanced amplifier: image 34i integrated tube amplifier - 35w x 2/ input 150mV/ 470K ohm ----------
I'm a novice and do not have much knowledge of hifi. My system seems to need attenuators as long as I do not want to use the software attenuation in slimserver. I've read some threads here and googled it, but couldn't get the clear answer to my questions. 1. There is a huge difference between the output voltage of my source devices and the input sensitivity of my tube amp. So I have very limited range of volume control on my amp. What could possibly happen if I turn the volume to max? (I never tried it.) What's the correct ansewer? 1) no volume increase over a certain level because it's limited by the preamp part of the circuitry. 2) It blows the power tubes. 2. 20*log(2100/150)= - 22.9 dB It seems my system needs 20~24dB attenuator to get the full range of volume control. But I don't understand what's the impact of the difference in impedance or what I need to do if any. 3. I've read it somewhere that an attenuator between a pre-amp and a power-amp usually works better than between a source and a pre(or integrated)-amp in terms of the sound quality. Has anybody tried to compare the sound qualities among no attenuator/source-attenuator-pre/pre-attenuator-power? 4. The prices of attenuators seem to vary and it does matter since I need four attenuators. Again for the sound quality, are those expensive ones worth? I would appreciate any answer or help. Thanks. -- smarco ------------------------------------------------------------------------ smarco's Profile: http://forums.slimdevices.com/member.php?userid=12178 View this thread: http://forums.slimdevices.com/showthread.php?t=36550 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
